Abstract

La présente invention concerne des technologies destinées à un traitement par hyperthermie de tissus malades, au moyen de particules conductrices. Des particules conductrices d'une composition et d'une distribution granulométrique connues peuvent être implantées dans un tissu malade et exposées à un champ magnétique alternatif, qui peut être réglé sur la taille des particules métalliques en vue d'induire des courants de Foucault produisant de la chaleur dans lesdites particules implantées. Lorsque la température des particules métalliques augmente, leur résistance s'accroît en raison de leur coefficient thermique positif de résistivité. Une antenne placée de manière externe au corps à proximité des particules métalliques peut faire partie d'un circuit radiofréquence réglé et être mise en résonance. Le changement de fréquence de résonance ou d'impédance de circuit peut entraîner un retour d'informations réglé, qui peut être utilisé pour réguler le traitement par hyperthermie.
